Hello Experts,

I am seeking guidance regarding an issue encountered with Purchase Order Prepayments in Dynamics 365 Finance & Operations.

Transaction Details

Original Purchase Order

Particular	Amount
PO Amount	97,666,730.00
VAT	4,883,338.00
Total PO Amount	102,550,068.00

Prepayment

Particular	Amount
100% Prepayment Created and Paid	102,550,068.00

Purchase Invoice

Particular	Amount
Purchase Invoice Posted Against PO	102,550,058.40
Prepayment Applied	102,550,058.40
Remaining Open Prepayment Balance	9.60

Subsequent Activity

In May 2026, the user mistakenly reversed the prepayment application for the following amount:

5,567,003.20

Problem Statement

When attempting to re-apply the prepayment, the system does not display the original Purchase Order (PO-000001046) against which the prepayment was originally applied.

Instead, the system shows an entirely different Purchase Order:

PO-000004712

which is unrelated to the original transaction.
When go to open prepayment form no open prepayment is visible against said PO.

Additional Observations

When navigating to the Reverse Prepayment window, the same invoice is visible; however, the Purchase Order reference is not displayed.
When reviewing the Prepayment Reversal Voucher, no related transactions appear on the Voucher form.
The original Purchase Order invoice remains posted, but the reversed prepayment amount cannot be re-associated with the correct Purchase Order.

Questions

Has anyone experienced a similar issue after reversing a PO prepayment application?
Are there any known limitations or data consistency issues that could cause the original PO to disappear from the prepayment application lookup?
Which tables or transactions should be reviewed to validate the relationship between the PO, prepayment invoice, and prepayment reversal?
Is there a recommended Microsoft-supported approach to restore the linkage and allow the prepayment to be reapplied to the correct Purchase Order?

Any insights, troubleshooting steps, or recommendations would be greatly appreciated.

Thank you in advance for your support.
